=== Fortifications ===
[[File:Other side of Moenjodaro by Usman Ghani.jpg|thumb|Excavation of the city revealed very tall [[Water well|wells]] (left), which it seems were continually built up as flooding and rebuilding raised the elevation of street level.<ref>McIntosh (2008), p. 118. "More than seven hundred wells were sunk at Mohenjo-daro when the city was built. Over the centuries houses were rebuilt and street levels rose; new courses of bricks were therefore added to the wells to keep their tops at the same height with respect to the street. The removal of earth and debris during the excavation of the city has left many wells standing like towers high above the exposed remnants of earlier streets."</ref>]]

Mohenjo-daro had no series of city walls, but was fortified with guard towers to the west of the main settlement, and defensive fortifications to the south. Considering these fortifications and the structure of other major [[Indus valley]] cities like [[Harappa]], it is postulated that Mohenjo-daro was an administrative center. Both Harappa and Mohenjo-daro share relatively the same architectural layout, and were generally not heavily fortified like other Indus Valley sites. It is obvious from the identical city layouts of all Indus sites that there was some kind of political or administrative centrality, but the extent and functioning of an administrative center remains unclear.
